Free Download Hp Laserjet 1100A Driver

I am running Windows 7 Home Premium, and have been trying to install the proper driver to use the scanner feature of my HP1100A(printer/scanner/copier). I had previously been using the HP1100 (MS) driver and the printer worked fine.I installed the '1100 series psc' driver from the pre-installed printer list, but now the printer no longer prints. Also an IEEE-1284 controller is now showing in my devices and printers window. When I try to print the 'Go' button lights and stays on while the next light blinks which indicates 'buffered data'. When I press the 'Go' button as instructed the page only prints a page with a line of lines and symbols at the bottom. Now, when trying to use the HP 1100 (MS) driver, the same lights appear and I get the same output at the page bottom.I suspect that the IEEE-1284 controller is the problem because when I previously printed using the HP1100 (MS) driver without the IEEE-1284 contoller the printer worked correctly.
